Definitions
- the invention relates to a process for the preparation of low-density soap/detergent bars for personal/fabric washing or for hard surface cleaning.
- the invention relates to a process for the preparation of low-density soap/detergent bars for personal/fabric washing or for hard surface cleaning in which a borate or borate-alumina structurant is generated in-situ to enable incorporation of high levels of water and other liquid benefit agents in the soap/detergent bars produced.
- TFM total fatty matter
- soap for personal washing contain over about 70% by weight total fatty matter (TFM), the remainder being water (about 10-15%) and other ingredients such as colour, perfume, preservatives, etc.
- TFM is generally the most expensive ingredient. Since the level of TFM needed for acceptable detergency is much lower than what is used in conventional toilet soaps, it is desirable to replace TFM with water, air or cheaper fillers, while retaining processability and good bar properties .
- Hard non-milled soaps containing moisture of less than 35% are also available. These bars have a TFM of about 30-65%. The reduction in TFM has been achieved by the use of insoluble particulate materials and/or soluble silicates.
- Milled bars generally have a water content about 8-15% and the hard non-milled bars have a water content of about 20- 35%.
- fabric washing composition as well as hard surface cleaners are produced in a bar form. These Bars require an acceptable physical strength to retain their structural integrity during handling, transport and use.
- the hardness of the bars, at the time of manufacture and subsequently, is an especially important property. Inclusion of certain ingredients to make the bar harder usually results in higher density bars, making the bars considerably smaller and thus less attractive to the consumer and also gritty to feel.
- borate compounds or boric acid in personal care products generally is not new.
- sodium tetra borate (Borax) has been used as a soluble scrubber in powdered hand soap compositions of the type used to clean medium to heavy soils found in industrial operations; or in liquid soaps.
- U.S. Patent No. 3,708,425 to Compa, et al. teaches a detergent bar containing about 5 to 60%' 'by wt . puffed Borax. This work specifically calls for puffed Borax or other puffed salts to which the user properties of the bar are attributed.
- U.S. Patent No. 3,798,181 to Vazquez teaches enzymatic detergent bars (not pure soap bars) containing 10-40% synthetic detergent, 0.5-5% enzymes, 5-40% binder (e.g., to help retain water) , 20-60% inorganic builder and 12-25% water. Borax may be used as possible inorganic builder.
- the bar is a detergent bar which contains enzymes unlike bars of the invention which contain no enzymes.

- Our copending application 810/Bom/98 discloses a process of preparing a low TFM composition by a reaction of fatty acid/fat with an aluminium containing alkaline material such as sodium aluminate solution that specifically has a solid content of 20 to 55% wherein the alumina (A1 2 0 3 ) to sodium oxide (Na 2 0) is in a ratio of 0.5 to 1.55 by weight gives superior bar properties. These bars have improved hardness and smoother feel. This reaction can take place in a broad temperature range of 40 to 95°C.
- an aluminium containing alkaline material such as sodium aluminate solution that specifically has a solid content of 20 to 55% wherein the alumina (A1 2 0 3 ) to sodium oxide (Na 2 0) is in a ratio of 0.5 to 1.55 by weight gives superior bar properties.

- a billet of soap is positioned under the wire such that the wire is just in contact with one edge of the billet.
- W g. weight
- the area over which the force acts will increase as the depth of cut increases and therefore the stress being exerted will decrease until it is exactly balanced by resistance of the soap and the wire stops moving.
- the stress at this point is equal to the yield stress of the soap.
- the time taken to reach this point was found to be 30 sees, so that a standard time of 1 min was chosen to ensure that the yield stress had been reached. After this time the weight was removed and the length of the cut (L in Cm) measured.
- the yield stress is calculated using the semi-empirical formula:
- Table 1 show that when the bar is formulated with the conventional material such as talc the level of water that can be incorporated is only up to about 13%. If the water level is increased, the bars are soft and difficult to process.
- the bars prepared according to the invention are processable at higher moisture levels.
- the bars according to the invention structured with 18% moisture showed ⁇ 6% weight loss at 45°C which was similar to the loss in the case of conventional soaps structured with talc having 13% moisture.
- the bars structured with talc and in-situ generated alumina with -18% water show 9-10% weight loss.
- the bars prepared according to the invention structure higher levels of water have good physical properties and retain higher % of this water during storage at higher temperatures in comparison to the conventional bars with similar water levels, while maintaining the sensory properties of high TFM soaps.
